Cummins QST30 is a large-displacement, high-power diesel engine launched by Cummins. As a core model of heavy-duty power solutions, it is specifically designed for heavy-load equipment under extreme operating conditions and widely used in fields such as mining, construction machinery, and power generation.

As a representative product of Cummins’ “Q Series” heavy-duty engines, the QST30 has a displacement of 30 liters and adopts a 12-cylinder V-type configuration. It boasts three core advantages: “high power density, strong environmental adaptability, and long service life”. Its technical foundation shares some common components with Cummins’ multi-fuel platform (such as the core structure below the cylinder head gasket), while the cylinder head and fuel system have been optimized for the characteristics of diesel fuel, balancing power performance and reliability.
